New York City, New York, United States

Boroughs
New York City is composed of five boroughs. Each borough is coextensive with a respective county of New York State. Throughout the boroughs there are hundreds of distinct neighborhoods, many with a definable history and character to call their own. If the boroughs were each independent cities, four of the boroughs (Brooklyn, Queens, Manhattan, and the Bronx) would be among the ten most populous cities in the United States.
- Manhattan (New York County; 2009 Est. Pop.: 1,629,054) is the most densely populated borough and is home to Central Park and most of the city's skyscrapers. The borough is the financial center of the city and contains the headquarters of many major corporations, the United Nations, a number of important universities, and many cultural attractions. Manhattan is loosely divided into Lower, Midtown, and Uptown regions. Uptown Manhattan is divided by Central Park into the Upper East Side and the Upper West Side, and above the park is Harlem.
- The Bronx (Bronx County: Pop. 1,397,287) is New York City's northernmost borough, the location of Yankee Stadium, home of the New York Yankees, and home to the largest cooperatively owned housing complex in the United States, Co-op City. Except for a small section of Manhattan known as Marble Hill, the Bronx is the only section of the city that is part of the United States mainland. It is home to the Bronx Zoo, the largest metropolitan zoo in the United States, which spans 265 acres (1.07 km2) and is home to over 6,000 animals. The Bronx is the birthplace of rap and hip hop culture.
